Why paper cup machine It is not recommended that customers frequently replace molds of multiple sizes？

Our machines can be changed with the different molds( different cup sizes) ,especially for the half set of molds (cups with the same bottom diameter and cup body angle) . However we do not recommend customers to change the molds frequently in machines due to the following 

reasons :

1.Replacing molds takes a lot of time

It takes time to change the mold , which causes the delay of production .  Even For an very experienced technician , it will take 1-2 hours to change a half set of mold , 1 day a full set of mold .

2.Testing after replacement will waste a lot of paper cup fans

After change with the mold , machines must be tested again for the production ,which causes the more waste of paper .

3.Easy to cause mold damage

During the change of molds , the spare parts of machines will be prone to the damage .

4.Too fast machines make mold replacement more difficult

For high-speed double plates paper cup machines , we strongly do not recommend to change the mold because there is the high risk of spare parts damage and production failure with the new mold .
